CDKN2A Gene Mutation
Information about Inherited Mutations
What is ?
is a gene that helps control cell growth. People who are born with changes—called mutations—in their gene have an increased risk for certain types of cancer.
Which cancers are associated with a mutation?
People with an in have Familial Atypical Multiple Mole Melanoma (FAMMM) syndrome. This mutation increases the risk for pancreatic cancer and melanoma. A small number of mutations may also increase the risk for nerve sheath tumors, sarcomas and other cancers.
Does everyone with a mutation develop cancer?
Although the lifetime risk for cancer with a mutation is high, not everyone with a mutation develops cancer. Following the guidelines for screening and prevention increases the chances of preventing cancer or catching it at its earliest and most treatable .
What can people with a mutation do?
Experts have created guidelines which estimate cancer risks and outline recommendations for managing these risks in people with a mutation.
There may be family planning concerns and options for people with an inherited mutation.

If you test positive for a mutation, you should inform your close blood relatives (first-, second-, and third-degree relatives) about your test results and encourage them to speak with a genetics expert.
